EUGENE MET'ILER, OF INDIANAPOLIS, INDIANA.

BOILER-TUBE CLEANER.

SPECIFICATION forming part of Letters Patent No. 776,478, dated.November 29, 190 1.

Application filed March 14, 1904.

To all whom it may concern:

Be it known thatI, EUGENE METTLER, a citizen of. the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Boiler -T ubeCleaners, of which the following is a specification.

The object of my invention is to produce a cleaner-head for the watertubes of boilers in which all of the parts are held in position by asingle bolt or nut and in which pins upon which the cutters rotatecannot work out of place.

The accompanying drawings illustrate my invention. 1

Figure 1 is a side elevation; Fig. 2, an end elevation; Fig. 3, asection on line 3 3 of Fig. 2; Fig. 4:, a section on line 4 4: of Fig.2, and Fig. 5 a modification.

In the drawings, indicates a shaft adapted to be connected by auniversal joint 11 or otherwise to a suitable turbine 12, mounted in themotor-casing 13.

Shaft 10 is provided with a head 14 and is threaded at its outer end.Splined upon shaft 10 and held thereon by nut 15 is a similar head 16.

Each set of cutters 17 is carried in a carrier which consists of a pairof mating castings 18, each of which is provided with aninwardlyextending lug 19. A pintle 20 passes through each pair of lugs19 and enters holes 21, formed in the inner faces of heads 14 and 16.The holes 21 should not be carried through heads 14: and 16, at leastfor their full diameter, thus preventing displacement of the pintle 20.

Drilled for its full diameter only partially through the end of eachcasting 18, parallel with pintle 20, is a hole 22. Mounted in the twoholes 22 is a shaft 23, upon which is journaled a desired number ofdisk-cutters 17 If desired, pintle 20 and shaft 23 may be made in twopieces and cast integral with castings Serial No. 198,012. (No model.)

18, as shown in Fig. 5; but in this case there should be suitablepolygonal mating portions 25 between the lugs 19.

It will be noticed that by removing the sin gle nut 15 the parts may beentirely disassembled.

I claim as my invention 1. In a tube-cleaner, the combination, with arotating shaft and head carried thereby. of a mating head detaehablymounted on the shaft, a cutter-carrier consisting of a pair'of matingparts, interacting axially-separable pivotal connections between thecutter-carrier members and the two heads, a cutter supported between themembers of-the cutter-carrier, and means for holding the detachable headupon the shaft and thus holding the cuttercarrier members and cutter inposition.

2. In a tube-cleaner, the combination, with a rotating shaft and headcarried thereby, of a mating head detachably mounted on the shaft, acutter-carrier consisting of a pair of mating parts, a cutter-shaftextending therebetween, a cutter journaled thereon, pintles for saidcarrier extending into the heads, and a fastening means for theremovable head.

3. In a tube-cleaner, the combination, with a rotating shaft and headcarried thereby, of a mating head detachably mounted on the shaft, acutter-carrier consisting of a pair of mating parts, a cutter-shaftextending therebetween but only partially therethrough, a cutterjournaled thereon, a pin extending through the mating parts of thecarrier and only partially into the two heads, and means for holding theremovable head to the shaft. In witness whereof I have hereunto set myhand and seal, at Indianapolis, Indiana, this 8th day of March, A. D.1904:.
